however when no checkbox is checked and one hits the select button i
get this error.
“NoMethodError (You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.each):”

i would like to either trap the error and display it in a “friendly way”
or not display anything at all.

i tried this in my view but it does not seem to help
<% if @items.length > 0 %>
